Air conditioning in general is a technology adopted to improve the quality of comfort in automobiles. But poor indoor air quality (IAQ) caused due to introduction of human load and surrounding in new generation automobiles reported adverse effect on the quality of passenger cabin. Excessive carbon dioxide (CO2) exposure can cause several health effects and even sudden infant death. Hence there is need to meet out quality of air conditioned cabin. This proposed investigation is focused on improving the indoor air quality by controlling the vital parameters like carbon dioxide, carbon monoxide, oxygen, Relative temperature, relative humidity and relative velocity which were used as indicators for IAQ and comfort levels in various systems functional and living environment. The above stated parameters have to be studied under various rates of air flow volume, fresh air supply and human load. These IAQ parameters are to be continuously monitored by a direct reading instrument and predicted thermal comfort index. This paper will improve the indoor air quality of passenger compartments and also improve thermal comfort and human comfort of indoor occupants.
